HARVESTING-KNIFE.

Specification of Letters Patent.

Patented June 23, 1908.

Application filed November 23, 1907. Serial No. 403,453.

To all whom it may concern:

Be it known that I, ADOLPH W. IHDE, a citizen of the United States of America, residing in Tyrone, in the county of Beaver, Oklahoma, have invented certain new and useful Improvements in I-Iarvesting-Knives,

of which the following is a full, clear, and eX- act description, reference being had to the accompanying drawing, forming part of' this specification.

My invention relates to a harvesting knife for use in cutting heads of grain from the stalks while standing in the field, the knife being more particularly designed for use in harvesting such grains as Kafir-corn, milomaize, dora-corn, rice-corn or other grains having heads similar to those mentioned.

The object of my invention is to provide a knife whereby the user may cut the head of grain from the stalk while grasping it by the same hand by which the knife is held, thereby providing for the use of both of the persons hands with a knife in each in order that the heads of grain may be harvested much more rapidly than they could be by using a common knife, in the use of which it is necessary to hold the head of grain in one hand and the knife in the other while severing the head from the stalk on which it has grown.

Figure I is a perspective view of one of my harvesting knives illustrated as it appears when held in the hand of a user and showing a head of grain grasped by the users hand with its stem in position to be cut by the knife. Fig. II is a perspective view of my knife shown in .the upright position in which it is'held previous to cutting action. Fig. III is a perspective view of the knife in the inclined position in which it is held during cutting action. Fig. IV is a longitudinal section taken on line IV-IV, Fig. III through the knife.

1 designates the shank of my knife which is provided with a plurality of holes 2 through which a strap is threaded to furnish finger loops 3 adapted to receive the fingers of a person s hand in order that the knife may be secured to the hand while in use. The finger loops may, however, be produced in any suitable manner other than by the employment of a strap as described. Near the inner end of the shank 1 is a brace finger 4 that is curved to fit the side of the hand adjacent to the little finger.

5 is the blade of the knife which adjoins the inner end of the shank 1 and extends laterally from each side of said shank. This blade is provided with an outer-cutting edge 6 extending throughout its length and one of the arms of the blade terminates in a cutting hook 7 to the point of which the cutting edge 6 extends. The knife is made adaptable for use in either the rightor left hand or in both the right and left hands of the user by locating the hook 7 at one end of the knife blade to make the knife suitable for use in the right hand and locating said hook at the other end of the blade to make the knife suitable for use in the left hand.

In the use of my harvesting knife the knife is secured to a persons hand by the user passing fingers of the hand through the finger loops 3 so that the shank 1 will be lo-v cated against the palm of the hand and the blade of the knife will be located adjacent to the little finger of the users hand. The user then, in the employment of the knife, grasps a head of grain as illustrated in Fig. I and, by moving the hand and the head of grain into a position at an angle to the stem of the head, imparts a twist to the hand while the cutting edge of the blade is resting against the stern of the head of grain and is thereby enabled to readily out said stem and sever the head from the stalk on which it has grown. The hook of the knife blade prevents said blade from slipping from the stem during the cutting action in the event of the blade being brought into contact with the stem near the end of the knife blade that is outermost relative to the persons hand in which the knife is held.

It will be readily appreciated that two of the herein described knives may be employed in the hands of the user with the same facility as a knife in one hand only, thereby enabling a person harvesting grain to sever the heads thereof from the stalks with twice the rapidity that is possible in the use of a knife of such nature as to render it necessary for the user to hold the head of grain in one hand while holding the knife in the other hand.

I claim:

1. A harvesting knife comprising a shank, a knife blade at one end of said shank and in plane therewith, the said blade being extended laterally from the shank, and the cutting edge of the blade being the edge thereof farthest removed from said shank, substantially as set forth.

2. A harvesting knife comprising a shank,

and a knife blade extending laterally from I a knife blade at one end of said shank exsaid shank and terminating in a hook, substantially as set forth.

3. A harvesting knife comprising a shank, and a knife blade extending laterally from said shank and terminating in a hook, and finger loops carried by said shanks, substantially as set forth.

4. A harvesting knife comprising a shank,

tending laterally from the shank, finger loops carried by said shank, and a brace projecting rearwardly from said shank, substantially as set forth.
